AB Pinta  is  caused  by  T  pallidum  subspecies  carateum.  It  occurs  endemically  in  rural  areas  of  Latin  America,  especially  in  Mexico,  Colombia,  and  Cuba,  and  in  some  areas  of  the  Pacific.  A  nonulcerative,  erythematous  primary  papule  spreads  slowly  into  a  papulosquamous  plaque  showing  a  variety  of  color  changes  (slate,  lilac,  black).  Secondary  lesions  resemble  the  primary  one  and  appear  within  a  year  after  it.  These  appear  successively,  new  lesions  together  with  older  ones;  are  most  common  on  the  extremities;  and  later  show  atrophy  and  depigmentation.  Some  cases  show  pigmentary  changes  and  atrophic  patches  on  the  soles  and  palms,  with  or  without  hyperkeratosis,  that  are  indistinguishable  from  "crab  yaws."  Unlike  yaws  and  bejel,  pinta  only  affects  skin  rather  than  both  skin  and  bones.  See  above  for  therapy.
